Need help about verifying a Facebook account.?

[Khrista]

I logged in my Facebook account then it said that i'm not using a real name in Facebook. Then there's this cellphone number verifying thingy. I typed in my cellphone number but I'm wondering I'm not receiving any confirmation text from Facebook. I can clearly receive a text from my friends but the code isn't in my inbox as well. So dunno what to do because if i'll not be able to receive one, i'll never be able to open my Facebook account
For Angel who answered my question: I did what you said but after I changed the password it appeared again. I have no other option to do but to verify a mobile number. What to do?

I think some persons reported your account as a fake one.So it's locked,try to verify it with other options.As there are plenty of users, sometimes the mobile verification code doesn't show up.So you may have to verify by the security question ( if you set that before ) or you have to verify photos. If no option from these two shows try to recover your account by clicking " forgot your password " on facebook page.
